Abstract
Material-Sensing Light Imaging, Detection, And Ranging (LIDAR) systems optionally include a laser configured to generate a light pulse, a beam steerer configured to produce a polarization-adjusted light pulse emitted towards an object, at least one polarizer configured to polarize reflected, scattered, or emitted light returned from the object, and a processor configured to detect at least one material of the object based on an intensity and polarization of the polarized reflected, scattered or emitted light from the object. The beam steerer may include a kirigami nanocomposite. Methods are also provided, including, for example, generating a light pulse, adjusting a polarization of the light pulse to produce a polarization-adjusted light pulse emitted towards an object, polarizing reflected, scattered, or emitted light returned from the object, and detecting at least one material of the object based on an intensity and polarization of the polarized reflected, scattered or emitted light from the object.
